Heavy quark thermodynamics with anisotropic lattices

Jon-Ivar Skullerud, Rachel Horohan D'Arcy, Gert Aarts +11

We present recent results from the FASTSUM collaboration, using anisotropic lattice QCD to study spectral properties of heavy quarkonia and open heavy flavour systems at high tempe…

Approaching the continuum with anisotropic lattice thermodynamics

Jon-Ivar Skullerud, Gert Aarts, Chris Allton +12

The FASTSUM collaboration has a long-standing programme of using anisotropic lattice QCD to investigate strong interaction thermodynamics, and in particular spectral quantities. He…

Finite temperature hadronic spectral properties

Ryan Bignell, Gert Aarts, Chris Allton +9

The FASTSUM collaboration has a long-standing project examining hadronic properties using anisotropic lattice QCD. We determine the spectral properties of bottomonia at finite temp…

Spectral properties of bottomonium at high temperature: a systematic investigation

Jon-Ivar Skullerud, Gert Aarts, Chris Allton +11

We investigate spectral features of bottomonium at high temperature, in particular the thermal mass shift and width of ground state S-wave and P-wave state. We employ and compare a…

NRQCD Bottomonium at non-zero temperature using time-derivative moments

Rachel Horohan D'arcy, Gert Aarts, Chris Allton +8

A well-known challenge for the lattice community is calculating the spectral function from the Euclidean correlator. We have approximated the spectral function and derived the mass…

Anisotropic excited bottomonia from a basis of smeared operators

Ryan Bignell, Gert Aarts, Chris Allton +9

Bottomonia play a crucial role in our understanding of the quark gluon plasma. We present lattice non-relativistic QCD calculations of bottomonia at temperatures in the range $T \i…
